(Table 1) List of samples with carbonate mineralogy, stable isotope, and accessory-mineral information

Petrographic and stable-isotope (d13C, d18O) patterns of carbonates from the Logatchev Hydrothermal Field (LHF), the Gakkel Ridge (GR), and a Late Devonian outcrop from the Frankenwald (Germany) were compared in an attempt to understand the genesis of carbonate minerals in marine volcanic rocks. Specifically, were the carbonate samples from modern sea floor settings and the Devonian analog of hydrothermal origin, low-temperature abiogenic origin (as inferred for aragonite in serpentinites from elsewhere on the Mid-Atlantic Ridge), or biogenic origin? Aragonite is the most abundant carbonate mineral in serpentinites from the two modern spreading ridges and occurs within massive sulfides of the LHF. The precipitation and preservation of aragonite suggests high Mg2+ and sulfate concentrations in fluids. Values of d18OPDB as high as +5.3 per mill for serpentinite-hosted aragonite and as high as +4.2 per mill for sulfide-hosted aragonite are consistent with precipitation from cold seawater. Most of the corresponding d13C values indicate a marine carbon source, whereas d13C values for sulfide-hosted aragonite as high as +3.6 per mill may reflect residual carbon dioxide in the zone of methanogenesis. Calcite veins from the LHF, by contrast, have low d18OPDB (-20.0 per mill to -16.1 per mill) and d13C values (-5.8 per mill to -4.5 per mill), indicative of precipitation from hydrothermal solutions (~129°-186°C) dominated by magmatic CO2. Calcite formation was probably favored by fluid rock interactions at elevated temperatures, which tend to remove solutes that inhibit calcite precipitation in seawater (Mg2+ and sulfate). Devonian Frankenwald calcites show low d18O values, reflecting diagenetic and metamorphic overprinting. Values of d13C around 0 per mill for basalt-hosted calcite indicate seawater-derived inorganic carbon, whereas d13C values for serpentinite-hosted calcite agree with mantle-derived CO2 (for values as low as -6 per mill) with a contribution of amagmatic carbon (for values as low as -8.6 per mill), presumably methane. Secondary mineral phases from the LHF for which a biogenic origin appears feasible include dolomite dumbbells, clotted carbonate, and a network of iron- and silica-rich filaments.

Chapter 2 On the usage of the measurements of geographical concentration and specialization with areal data

Measures have been developed to understand tendencies in the distribution of economic activity. The merits of these measures are in the convenience of data collection and processing. In this interim report, investigating the property of such measures to determine the geographical spread of economic activities, we summarize the merits and limitations of measures, and make clear that we must apply caution in their usage. As a first trial to access areal data, this project focus on administrative areas, not on point data and input-output data. Firm level data is not within the scope of this article. The rest of this article is organized as follows. In Section 2, we touch on the the limitations and problems associated with the measures and areal data. Specific measures are introduced in Section 3, and applied in Section 4. The conclusion summarizes the findings and discusses future work.

A New Method to Retrieve, Cluster And Annotate Clinical Literature Related To Electronic Health Records

The access to medical literature collections such as PubMed, MedScape or Cochrane has been increased notably in the last years by the web-based tools that provide instant access to the information. However, more sophisticated methodologies are needed to exploit efficiently all that information. The lack of advanced search methods in clinical domain produce that even using well-defined questions for a particular disease, clinicians receive too many results. Since no information analysis is applied afterwards, some relevant results which are not presented in the top of the resultant collection could be ignored by the expert causing an important loose of information. In this work we present a new method to improve scientific article search using patient information for query generation. Using federated search strategy, it is able to simultaneously search in different resources and present a unique relevant literature collection. And applying NLP techniques it presents semantically similar publications together, facilitating the identification of relevant information to clinicians. This method aims to be the foundation of a collaborative environment for sharing clinical knowledge related to patients and scientific publications.

Forest Hydrology, Soil Conservation and Green Barriers in Canary Islands

In volcanic islands, the rainfall regime and its torrential nature, together with the steep slopes and the soil types present are considered to be some of the main factors affecting forest hydrology and soil conservation. In such environments, rain regime is generally irregular and characterized by short and intense rainfalls, which could cause destructive flows at times, followed by long periods of rain absence. The volcanic nature of these islands have as a direct resultant steep slopes which influences the runoff volume and speed, as well as the amount of topsoil susceptible to be detached and transported downstream. The soil type also affects the susceptibility to erosion processes. Andisols are the most typical soil on volcanic islands. Their particularities derive their mineral constituents, called short-range-order products, which provide these soils with an increased structural stability, which in turn reduces their susceptibility to erosion. However, the land use changes and the environmental factors such as rain regime and steep slopes may be determinant factor in destabilizing these soils and ultimately a cause for soil erosion and runoffs, which become a threat to the population downstream. Green barriers have been traditionally used to prevent or reduce these processes, also to enhance the dew effect and the fog water collection, and as a firebreak which acts as a barrier to slow or stop the progress of a wildfire. Wooded species present and subsequently their performance have a major influence on their effectiveness. The use of this natural erosion and fire control methods on volcanic islands is discussed in this paper.

Technology of bare tether current collection

The outstanding problem for useful applications of electrodynamic tethers is obtaining sufficient electron current from the ionospheric plasma. Bare tether collectors, in which the conducting tether itself, left uninsulated over kilometers of its length, acts as the collecting anode, promise to attain currents of 10 A or more from reasonably sized systems. Current collection by a bare tether is also relatively insensitive to drops in electron density, which are regularly encountered on each revolution of an orbit. This makes nighttime operation feasible. We show how the bare tether's high efficiency of current collection and ability to adjust to density variations follow from the orbital motion limited collection law of thin cylinders. We consider both upwardly deployed (power generation mode) and downwardly deployed (reboost mode) tethers, and present results that indicate how bare tether systems would perform as their magnetic and plasma environment varies in low earth orbit.

Reality bites: Documentary photography and architectural realism = Fragmentos de realidad: Fotografía documental y realismo en arquitectura

En el día de hoy nos enfrentamos a una serie de desafíos económicos, geopolíticos y ambientales que apuntan hacia una transformación profunda del mundo tal y como lo conocemos. La arquitectura esta – siempre lo ha estado – imbricada en todos estos problemas. En nuestra actual condición de recursos limitados e injusticia global surge la necesidad de superar la dicotomía entre progreso y tradición, entre innovación y preservación – la urgencia de redefinir incluso cada uno de estos términos. Los tipos de crisis que encaramos ahora no se resolverán con mas tecnología y más crecimiento – se necesita también una profunda reevaluación de nuestros sistemas de valores e incluso de nuestra sensibilidad. En este contexto, la humilde contribución de esta tesis consiste en proponer la idea de un realismo en arquitectura, entendido como una actitud progresista y atenta a lo que ya existe, dispuesta a abrir los ojos al presente, a las condiciones y los problemas reales que nos rodean. Pensando en esta idea, resulta evidente que si bien el realismo carece de una definición clara en el campo de la arquitectura hoy, cuenta sin embargo con numerosos precedentes parciales, entre ellos algunos de los más notorios episodios de la historia de la arquitectura reciente. Al intentar confeccionar una lista provisional de arquitectos realistas en el último siglo, otro hecho se nos presenta: muchos, por no decir todos estos arquitectos, comparten una fijación por la fotografía, bien apropiándose del trabajo de fotógrafos contemporáneos, bien tomando sus propias imágenes como una forma de mirar fuera de sus estudios e incorporar la realidad del medio construido a sus proyectos. Parece entonces lógico pensar que la arquitectura, como disciplina visual, ha acudido a otra disciplina visual en búsqueda de su propia respuesta al problema del realismo – dentro de este campo la fotografía reverbera con la arquitectura especialmente, ya que ambas son consideradas simultáneamente como practicas utilitarias y como parte de las bellas artes. Parece entonces lógico el organizar la investigación como una serie de casos, con la esperanza de que la acumulación de diversas instancias en las que la arquitectura ha acudido a la fotografía en su búsqueda de un realismo arrojara luz sobre las ideas más generales a debate. Por tanto, cada uno de los episodios en este texto se examina en sus propios términos, si bien una serie de interconexiones emergen a medida que el estudio procede con un suave orden cronológico. Hacia el final del texto cuestiones más grandes recobran protagonismo, a medida que las repercusiones políticas de nuestro estudio se hacen más patentes y comenzamos a interrogar las implicaciones contemporáneas y el potencial futuro de nuestra discusión sobre el realismo. ABSTRACT Today we are faced with a series of economic, geopolitical and environmental challenges that outline a deep transformation of the world as we know it. Architecture is – it has always been – ingrained in all of these problems. In our current condition of limited resources and global inequalities there is a necessity to overcome the dichotomy between progress and tradition, between innovation and preservation – an urgency to even redefine these terms altogether. The types of crises that we are facing will not be solved with more technology and more growth – a deep reevaluation of our systems of values and our sensibilities are also needed. In this context, the humble contribution of this text is to put forward the idea of an architectural realism, understood as an attitude that is both progressive and attentive to what is already in place, willing to open its eyes to the present and accept the real conditions and problems around us. In thinking about this prospect, it immediately becomes apparent that even if realism lacks a clear definition in the field of architecture today, there are numerous partial precedents for it, among them some of the most notorious episodes in the recent history of architecture. In crafting a tentative list of realist architects in the last century, another realization takes place: many, not to say all of these architects, have had a fixation with photography, either appropriating the work of contemporary photographers or taking photographs themselves as a way to look out their windows and bring the reality of the built environment into their practices. It seems then logical to think that architecture, as a visual discipline, has looked to other visual disciplines in search for its own take on the problem of realism – within this field, photography specially resonates with architecture, since both are regarded simultaneously as utilitarian practices and belonging to the fine arts. The idea then becomes to organize the research as a series of cases, with the hope that the accumulation of diverse instances in which architecture has approached photography in its realist drive will shed some light on the larger ideas at stake. Therefore, each of the episodes in this text is examined on its own terms, with a series of interconnections slowly emerging as our survey proceeds with a soft chronologic order. Towards the end of the study, larger issues regain relevance as the political repercussions of our inquiry become more pressing and we start to question the contemporary implications and future potentials of our discussion on realism.

Contribuciones para el tratamiento de aguas residuales con sistemas alternativos de bajo coste. Aplicaciones para el desarrollo en poblaciones reducidas y cooperación

Este trabajo se ha centrado en la búsqueda y análisis de técnicas de saneamiento y depuración que proporcionen soluciones a poblaciones pequeñas, que por su situación económica o de desarrollo, carecen de estos servicios básicos. Es bien conocido los problemas que genera la falta de acceso al saneamiento básico en contextos de subdesarrollo, agravado en numerosos casos, por los incrementos en la dotación de agua sin introducir las infraestructuras para el tratamiento de las aguas residuales. Esta situación incide directamente sobre la salud de las personas y del medioambiente. Afortunadamente existen Organismos Internacionales y Agencias de Desarrollo y de Medioambiente, que intervienen directamente en estos temas. Los problemas no sólo se presentan en los llamados países en vías de desarrollo, sino que se ha comprobado que también afecta a poblaciones pequeñas con escasos recursos, del mundo más desarrollado. Muchas han sido las técnicas utilizadas con gran éxito en programas de cooperación, pero algunas han fracasado por pérdida de funcionalidad, por errores de diseño, por rápido deterioro de los materiales, o simplemente por falta de adaptabilidad al terreno o no previsión de controles y mantenimiento. La solución a estos eventos pasa por la innovación tanto tecnológica como de gestión, sin olvidar la componente socioeconómica y cultural. Tomar conciencia de un buen diseño adaptado a las características del terreno y de la población, evitaría fracasos por colapso, por falta de mantenimiento, de financiación etc. Por otra parte, se considera necesaria la implementación de programas educativos que incluyan mejoras en los hábitos higiénicos y el conocimiento de las infraestructuras que permitan a la población de destino, adquirir una formación sobre las propias instalaciones, su uso, su mantenimiento y conservación. El desarrollo y mejora de las técnicas de saneamiento y depuración requiere una continuidad en las investigaciones que facilite la adaptación de las instalaciones ya existentes a las diferentes coyunturas que puedan presentarse, garantizando su funcionamiento a largo plazo. Las técnicas denominadas “no convencionales” se caracterizan por ser soluciones económicas y sostenibles, que en algunos casos, requieren poco mantenimiento e incluso éste puede realizarse por personal no especializado, esto es, por los propios usuarios del servicio. Concretamente en el presente trabajo se ha llevado a cabo una revisión general de las tipologías conocidas, tanto convencionales como no convencionales y de su posible aplicación en función de la población de destino, con especial incidencia en las poblaciones más desfavorecidas. Una vez realizada, se han seleccionado las técnicas de saneamiento y depuración no convencionales por el interés personal en las poblaciones con mayores dificultades socioeconómicas. Se han estudiado distintas situaciones en diferentes países y contextos Nicaragua, Ecuador, India y España. Es en esta última, donde se han tenido más facilidades para la obtención de datos y análisis de los mismos, concretamente de la instalación del municipio de Fabara en la provincia de Zaragoza, situado en el Bajo Aragón. ABSTRACT The focus of this project lies on the research and analysis of sanitation and waste water treatment techniques able to provide solutions to small settlements which lack such basic services out of economic or underdevelopment reasons. The problems generated by the absence of access to basic sanitation services in underdevelopment contexts are well known, and many cases can be found where increase of water provision doesn’t involve installation of waste water treatment infrastructures. This situation has a direct impact on people’s health and also on the environment. Fortunately, there are International Organizations and Development Agencies which act directly on these matters. These problems don’t only occur in so called developing countries, as it has been confirmed that small settlements with scarce resources in the more developed world can also be affected. Many techniques have been successfully used in cooperation programs, but also some of them have failed due to loss of functionality, design mistakes, rapid material deterioration, or simply site inadequacy or lack of control and maintenance precautions. The solution to these incidents requires technological as well as management innovation, regarding for all cases the socioeconomic and cultural factors. The awareness of a good design, adapted to the site and population characteristics, would prevent from failures due to collapse, lack of maintenance, funding, etc. Furthermore, the implementation of education programs for improving hygienic habits and for transmitting the understanding of the infrastructures is considered necessary for allowing the aimed population to gain proper knowledge on their own infrastructure, its use, maintenance and preservation. The improvement of sanitation and waste water treatment techniques requires a continuous process of investigation, in order to adapt the existing infrastructure to the different situations that may come up, being able to ensure its long-term functioning. The so called non conventional techniques are characterized by being economic and sustainable solutions, requiring in some cases low maintenance, conducted even by non specialized personnel, that is, by the users themselves. In the present project a general overview of the already developed typologies has been carried out, taking into account the conventional as well as the non conven tional techniques and their possible application according to the aimed population, regarding especially the most underprivileged settlements. Thereupon, out of interest for the settlements with most socioeconomic difficulties, the non conventional sanitation and waste water techniques have been selected. A variety of situations in different countries and contexts has been examined, specifically in Nicaragua, Ecuador, India and Spain. The latest has proven easier for data collection and analysis, focusing finally on the existing infrastructure in the village of Fabara, province of Zaragoza, in the Bajo Aragón.
